Question

我有使用Spring Security 3.1保护的GWT 2.5应用程序。当我想添加Spring Beans来使用DB时，我遇到了奇怪的异常。当我添加到appcontext.xml行<context:component-scan base-package="com.server" />时，部署后我得到了

java.io.FileNotFoundException: class path resource [javax/servlet/http/HttpServlet.class] cannot be opened because it does not exist

或

java.io.FileNotFoundException: class path resource [java/lang/Object.class] cannot be opened because it does not exist

所有人都使用maven成功构建。部署到Tomcat 7.0.37 x64时出现问题。当我评论此行时，错误消失。我尝试重新安装Tomcat / Java，所以情况并非如此。可能是什么原因？

UPD 我可以发布我的xml配置文件，如果这可以帮助。

因此， com.server 包含我的所有服务器类，spring bean和servlet。

@Srinivas 我在pom中有这种依赖性。但无论如何，如果是这样，为什么没有找到普通的Javas Object.class？

  <dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
